Abstract :
The Japanese advanced cruise-assist highway system (AHS) provides driving support services through collaboration between the system and vehicle. AHS uses dedicated short-range communications (DSRC) for road-to-vehicle dialog that requires real-time and high-reliability operation. AHS-DSRC constitutes a small radio zone that provides driving support information in a cycle of 0.1 seconds. DSRC incorporates a marker beacon and an information beacon that are successively positioned at the roadside. This paper describes the AHS-DSRC was verified by experiment to provide a safety level of 99.1% or better.
